Abstract
A pipe lining material is inserted into a pipeline and expanded to press against an inner peripheral surface of the pipeline. Hot water from a first fluid source is sprayed onto the pipe lining material via a hose to cure the thermosetting resin impregnated therein and thereby cure the pipe lining material, with the sprayed hot water being accumulated in a bottom part of the pipe lining material. The hot water accumulated in the bottom part of the pipe lining material is delivered to a second fluid source separate and independent from the first fluid source, cooled in the second fluid source to provide cooling water, and supplied to the hose. The cooling water is sprayed onto the cured pipe lining material via the hose to cool the cured pipe lining material.
